The burner proper consists of pipes orfhollotv ixtures'- 9V yr ectan'gularly arrangedjfand preferably provided with reinforcing or strengthening ribs or edgesflO.

Extendingiroin the burner are arms 11 and 12,1espectively. ofthese arms the arm ll-.is a .hollow r`arinfthrough which gasis ad.-

niitted; tothe burner. Thisy 'ar-in connects with a mixing tube 13 'which extends through the'side Wall ofthe extensionfof the oven above'the bottomfof the extensin,

andlprovides one of the tru'nnions upon which the burner mounted to swing. The other arm l2 of the burner isfitted with a turned endlll which formsthe other trunnionxfor the burner, thesame turning within a bearing located at the rear of' the oven above the bottom of the' extension 'opposite the bearing of ,the mixing tube or- ,trunnion 13.

In point of structure, the burner, its respective arms and trunnions, of which one comprises a mixing chamber, are preferably made of integral construction asshown.

The arrangement and extension of the arms 1l and 12 bearing the burner and the `location of the bearings of the respective Y trunnions are such thatthe burner may be 10 of thev burner has bearing t burner.

turned to assume a, downturned operative position as shown in'Fig. 3 or yanupturned out-of-the-way and inoperative )ositionas shown in Fig. 4. When inits ownturned operative position the burner will lie in close proximity and vsubstantially parallel withl the bottom of the Voven with a forward extension to a point about midway the ovenV the burner tubes having preferably aglateral extension of about the ltull width of the oven. When inI its downturned or operative positionv the burner is supported by `lugs 16 projecting from'the opposite sides ofthe oven and against which the outturned rib or edge Itv will also be-observed that the tubes 9" of thev burnerVV are provided` with ports V18 formed upon the under side thereof and out at an angle so that the flame issuing from the burner will project at an angle of about,-

459 in the directionuof the bottom of the oven,` 'but owing to the angularity of their projection and the spacing of the burner from the bottom of the oventhe flame does `not have contact with thebottoin of` the oven.

.i flVhen the burneris swung to its upturned inoperative` position itwill-flie `slightly oflj' centre and bear against the rearend of the oven, maintaining `its .position bylgravity.

Gas is supplied to the burner through a pipe connection 2() havingaverticallyfdisposed portion2l at the end ott the range and which portion at the bottone end thereof is provided with a pipe connection"22y which maj-kes a tight though swing-joint connection with the end of the mixingtnbe as shown inFig. A"

The burner is turned. to and between its downturned and upturned positions by means of' av lever 24. To the end ofv this lever is pivotally secured a link 25 which is pivot-ally secured to an arm 26 projecting from the side of the mixing tube 13- constituting one of the trunnions supporting the The lever 24 is fulcrumed to turn uponfaboss 27 projecting frornthe end of the stove and to which theleveris secured by a pin 28V.y The outer end of the lever projects through a slot 29 in a bracket 30 at slot 29 andto the lever the front of' the stove. Beyond the bracket the lever is provided with a handle 31 for operating it. j Y

With theparts thus arranged the burner will be thrown into its downturned or operaf ytive positionr by throwing down the handle of the lever, and to its upturned or inop-V erativejposition by lifting the handle or end of the lever; The slot 2S) is made of ample length to admit of the lever having sufficient play to effect a proper turning of the burner into its respectiveiturned positions and in practice is made of such lengththat the ends 33 and 34, respectively,l of the slot will define, by the engagement of the lever with them, the properly turned positions,

effected by means of a loose jointxor coupling 37 of ordinary type. The outer endof'the rod projects throughthe bracket 30` ata point laterally Vadjacent the slot 29 and a little distance 'beloivthef top end of 'the slot. Y y knob or handle 38 for turningit.

.9,5 The rod 36'is provided with 'a I Projecting laterally from thesideof the I `rod 36 is a stud '40. This stud as the rod is turned is adapted to engage one or the other of stops 4:1, 4:2, formed upon the front side of the bracket 30. These stops define the opening and closure of the valve 35, the engagement of the stud With the stopr 4:1, de-

fining the open positionv of the valve, "andthef stop (lf2 Ainl closedV position. orallyv from the rod 36 at thel Yrear ofA the bracket is a finger The relative location of the rody 36 and linger43 uponit to the @it and also the length of the` finger .arefsuch of the slot 29 with the hurnerthrown into its inoperative position. the ivalve will he closed and the linger sl'iifill have engage nient with the side `of the lever. The lever will then prevent the valvebeing turned into an open the position of therlever has been changed for moving the burner into its downturncd operative position, then the rod 36`1nay be turned for opening the valve, the .finger then being'turned to extend across the slot29.

. The advantage of this arrangement is that the gas cannot be turned on as long as the burner is in its inoperativ'eposition, and can only beturned on when the lever has been thrown down for turning the burner intoits operative position. When the burner is in position Aas long as the lever remains at the upper end of the slot. Then Projecting 'neY that when tliefhanudle of the lever is drawn up tothe upperend` iis pur o y is placed Withintlie oven upon an oven rack with matter now to be referred to. s

-its operative position and the' gas turned on,

tlliefingervwill then be extending across the the burner -throivn up into its inoperative position bythe lifting' of the lever7 the lever will .engage 4the linger and automatically turn olf the gas.

Then the' burner is' in operation for the seo'f baking, the article to be cooked t5 supportedby ilangest@ projecting from thesidee oli the oven" in -tlieueual manner.

Inorder to prevent the heatfr'oni the burner ris-ing directly against the article and to as sist in disseminating the" heat troni the burner trl'i-roughout, ythe oven; afbattle vMis provided-1 above the 'burner andbeti'veen itralnd the oven rac'lr'L-. This balefor'ins apart of', orV isv supported by, a rack-48, which is slid linto `and out of vthe oven-v andsupport-ed by tlanges 4G on the sides of the oveny the saine' as the oven rack. A sufhcient number of flanges ong-the `sides of the oven :are providedsofthat'the baille may lfJeset` at different adjusted spaced positions freni-thek burner. Under certain: conditions, vvhen certain articles are tobe baked, thebaiile may kbeset `very close" totheburner and the oven rack supporting' the article brought doWn relatively close to thebailei Under other circumstances changed relative positions of kthe `bali(eL-supporting' rack and ove'nrackare des-iiable` all of Which are provided for'in the arrangementV shown. That is, the `baille kmay "beset at any properly adjiueted posit-ion in relation `to the burner; li'lreivinefthe oven rack supportingtlie article; The baffle-sup porting rack isindicated in det-'ail'in Fig. 6 Where' it liaseenl thatthe baille properv is one such as to substantially cover fthe burner, and the rack isiothervvi'se made perforated throughout so as not to interfere with-fa proper circulation ofv heat at the front and sides of the battle. 1 i

"In this connection it Willbe observed that the badie-eiqiporting`rack7 as likewise-thc oven rack, extend bac-li` into the oven only to the point Where the extension 3 oil the oven begin'systope Litt being provided for the racks. A space is accordingly leftbaek of they balile and o'venplate up through the extension 8 of the oveinfwhich is signiticantin courier-tion When the burner is in operation for the purpose of baking, air is admitted to the front of the oven at the bottom through an opening 51 inthe oven door 52. This opening is controlled by a lslide 53. An. outlet is provided from` the chamber offthe oven through the openinge int-o4 the iue y6 in the top of the oven and thencev out through the opening? into the bach flue andoutlet ot the ran-ge, as beforepointed out.- The passage through the flue6`a1id Opening 7 s con# air inlet and outletopenino@ 'as Well as baking.

trolled :by damper 54 having `secured toit a curved arm 55 provided with a turnedend. The damper is located outside the oven with lthe arm extending through the opening 7 into thek flue 6 and thence down through the bottom Yozt the fluey into the chamber ofy the oven. The arrangement and relationehipof the parte are suchthat'the damper will gravitate to anormal :open vposition and will be moved to closed position bythe lengagement of the` burner with the turned endv o .the arm when theburner is moved 4into its upturned or inoperative position?` substantially aSehown in Fig. 4. That is, the arrangeinent is Suchy that When the` burner is turned down Within the oven for nirp'oses ot' use, the damper will automatically b e releasedto' open, and ivhenrthe burner is turned up into its outeof-the-Way position, the damper is automatically closed for n'iahing a tightoven, the slide 58 being then #closed by hand. t .y f y The relative disposition or' the respective C. together with the r,disposition .of theI .burner and v baitie is such that `as the air enters through the inlet kopening` 5l. in Vthe frontv .at thel bottom oi the oven it vWill passto the burner'for supplyin'g air thereto and thence I noceed beneathithe burner and upwardly back of' the burner and battle thro'ugl'i the extension 3 of theoven and thence iorw'ar'd to the' trent-of theL ovenvivith the etilecty offcreating' a circulation 4of air Within the -ovenvvhich acts to -properly disseminate the .heat throughout vSO that as the coolnirflentera the oven will .Y

The burner is maintained in' this position byineans of a latchtor finger 58 located inside the bracket 3() upoira pin` or Stud 59: arrangedjto turn Within thebrachet and fittedl on "the outer side of the bracket with a knob4 or headGO by Whichit may beturned The pin isx'located at a'point'laterally adjacent the slot 29 in the' bracket valittle 'distance above thev bottoni ot the slotyfznidthe extention `ot y"the pin is such that when turned into a substantially horizontal position it will cross the Aslot Q9. lVhen so'extended the pin will bear against a stop 6l upon the inner face of the "bracket, Thus supported and crossing the slot oi' the bracket, the finger will act as a stop or rest against which the lever 24 may bear when supporting the burner in its angular position suitable for broiling, the weight of the burner actingto hold the lever against the finger. When Vit is desired to use the burner for purposes of broiling, the finger is simply turned down to cross the slot and the lever then brought down to rest upon it.
